CONSTRUCTION OF REENEORCED-CONCRETE FLOORS, ETC.

Application led December 19, 1925. Serial No. 76,369.

Y tained, all as hereinafter fully set forth.

In the accompanying drawings I illustrate a practical embodiment of the essential features of my invention as applied to the construction of a concrete floor, a portion of which is shown in section with they formative means mainly in elevation, although I do not limit myself to the identical struc-A turc of parts and appurtenances shown by way of exemplification, since changes 4may be made in minor details, and equivalent mechanical expedients resorted to with like results. and Without departing from the spirit and intent of Vmy invention in this re- Y spect.

With this understanding Fig. l represents a sectional elevation of two adjacent formative truss-units and adjunctive parts, together with superposed concrete;

Fig. 2 is a longitudinal sectional elevation, taken upon plane of line 2 2, Fig. l, of three truss-units and adjunctive parts in alignment, broken away between successive truss-units Fig. 3 represents lthe portion of concrete floor shown in Figs. l and 2, after the removal of the formative supporting means, andillustrating the use of ceiling panels as applied thereto;

Fig. 7 is a perspective view of one of the truss-units Fig. 8 is a perspectiverview of a portion of one of the ioor matrix plates; v v

Fig. 9 is a perspective View of one of the longitudinal connective spacing rods, broken away medially;

Fig. l() is a detail view of connection between superposed parts of matrix plates.

The object of my invention being, primarily, the formation of a continuous integral concrete structure C, having parallel trapezoidal portions C', which function asl joists to the intervening portions thereof,as will be understood by reference more particularly to Fig. 3, of the drawings, I herein set forth the means and method employed in the attainment of a floor and ceiling con- 1 struction, with the understanding that essentially the same means and method may be utilized in the formation of a wall or analogous partition of a building or enclosure.

To this end I first position a parallel series of twin supporting` girders or beams B, at the requisite distance apart to afford space for the truss-units "T, to be used in the formationiof thesuperstructure as illus .trated in the firstk two figures of the ings.

'Each truss-unit T, one of which is shown drawin perspective in Fig. 7, of the drawings,

consists of twin brace sections T, T", oneof which is shown in perspective detail in Fig.'

6. Each brace section T, consists of a inetallic base plate t, to which is rigidly secured an upright member t, formed with a lateral extension t2, the other extremity of which is vrigidly connected with the base plate t, by

means of a diagonal brace 3. The opposed upper portions of the upright members t', t', of the brace sections T, T, are inclined and curved inward as related to each other inthe making of a truss-unit T, the ends of said lateral extensions t2, t2, overlapping to constitute the top of the arch of the trussunit T.

The base plates t, t, are of sucient length to overlap centrally as incorporated in the truss-unit T, and are formed with coincident holes t4, t4, for the accommodation of bolts a, a, provided with nuts a', a', by means of which the two base pla-tes t, t, of a trussunit T, are rigidly attached.` The lateral extensions t2, t2, are also formed with coincidental slots t5, 5, for the accommodation of the shouldered ends of the spacing bars s, s, which are interposed between the trussy units T, as shown more particularly in Fie. 2, of the drawings.

The base plates t, t, of the twin sections T, T, protrude suilieiently beyond the upright end members t, t', thereof, to admit of insertion between the superposed beams B, B, as shown in Fig. 1, oit the drawings, thereby affording adequate support tor each truss-unit T.

When the truss-units T, are thus positioned upon and between adjacent rows ot parallel twin supporting beams B, matrix plates M, are laid upon and between adjoining truss-units T, and over the spacing bars 8, s, said matrix plates M, being of sufiicient length for the purpose7 and two being provided for each span,one for each side ot the arch thus formed, said plates M, overlapping each other centrally so as to cover and enclose the truss-units and the spaces therebetween, the lower edges m, of said matrix plates M, being interposed between the truss end members t, t', and the supporting beams B. B, and said lower edges 0n, m, resting upon the base plates t, 2f. of the truss-units and against the adjacent sides of the beams B, B, as shown more particularly in Fig. l, of the drawings.

Adjacent to said lower edges m, of the matrix plates M, they are termed with externally protuberant longitudinal ribs m',y

m', which not only constitute shoulders for resting against the upper beams B but also function as means whereby grooves c, c, are created in the joist-lilre portions C, ot the cast .attained by lling the moulding space above the matrix plates M, with concrete. These grooves c, c, atlord .support for the ceiling panels 0, between the joist portions C', of the cast as indicated in Fig. 3, of the drawings.

Metallic reen'forcing and binding wires fr, are imbedded inthe concrete filling ot the mould space above and between the matrix plates lll.

The overlapping' edges of the matrix plates are -formed with periorations m2, for the acconimodation of wire binders m3, as shown in Fig. l0, of the drawings.

That I claim as my invention and desire to secure by Letters Patent. is:-

l. A truss-unit of the character described comprising twin brace sections each consisting of a base member and an angular member having one end secured to the base member, the two sections being relatively arranged with their base members overlapped and secured together, and portions of the angular members overlapped and .secured to each other, and diagonal braces disposed with their ends secured to the base member and to the overlapped portions of the angular members.

2. A truss-unit oit the character described comprising twin brace sections each consisting of a base member and an angular member having one end secured to the base member, the two sections being relatively arranged with their base members overlapped and secured together` and portions of the angular members overlapped and secured to each other, and diagonal braces disposed with their ends secured to the base members and to the overlapped portions oi the angular members, said braces being crossed at substantially their centres.
